a Medieval Jew carrying wine for the Sabbath
The other day I was reading an article that a good friend sent to me about the fast of the Ninth of Tevet. Although we don’t hold by it these days, according to Prof. Sid (Shnayer) Z. Leiman, “Scroll of Fasts: The Ninth of Tebeth,” Jewish Quarterly Review (n.s.) 74.2 (October 1983): 174-195, in the middle ages and earlier, Jewish communities would fast on the 9th and not on the 10th. Although this fact alone was pretty interesting, the reasoning and the contested and argued history of why this was decreed was truly amazing.One reason for the fast was to negatively commemorate the the birth of Yeshu (Jesus) and the begging of the Christian religion which had, especially in the Middle Ages, caused Jews so much pain and distress. As so many believe today, and far more people believed in Middle Ages, Yeshu was born on December 25. Today many historians put his birth date in the summer, but the decision to fast was based on the original assumption. It was figured out that December 25 in the year of his birth matched up with the Ninth of Tevet, thus the fast.
The second reason is far more intriguing to me. It seems that with the initial success of the apostles to bring new people into their religion came a lot of fear in the hierarchy of the Jewish community. Within the first few generation it was secretly decided that a knowledgeable Rav should infiltrate the clergy to the highest ranks in order to derail the conversion effort facing the Jews and refocus those efforts towards Pagans. Whether or not this actually happened, it could explain why Pagans were targeted for mass conversion. It was centuries before Jews were targeted all over Europe in the violent way that forced so many of our brethren to convert. When this Rav passed away, on the Ninth of Tevet, a fasting was enacted to mark his achievements in saving our people from possible extinction.
I love finding out random tidbits that I never knew about especially in our Medieval history. [Thanks MB (Jastrow)]
